Abstract

The utility model discloses a single-pass perfusion apparatus, which mainly comprises an air pump 1, a pressure gauge 2, an air storage tank 10, a liquid storage cylinder 9, an indwelling needle 8, a liquid refilling valve 4, a constant-pressure regulating valve 3, a liquid refilling spool 5, a spring 6, a regulating bolt 7 and an air filter 11. The single-pass perfusion apparatus is structurally characterized in that an inlet of the air pump 1 is connected with the air filter 11, an outlet of the air pump 1 is connected with the air storage tank 10, the pressure gauge 2 and the constant-pressure regulating valve 3 are mounted on the air storage tank 10, the air storage tank 10 is connected to the upper end of the liquid storage cylinder 9, the indwelling needle 8 is inserted to the lower end of the liquid storage cylinder 9, the liquid refilling valve 4 is fixedly connected to the side of the liquid storage cylinder 9, the liquid refilling spool 5 is mounted in the liquid refilling valve 4, and the spring 6 is sleeved on the liquid refilling spool 5 and pressed by the regulating bolt 7 fixedly. The single-pass perfusion apparatus has the advantages that air pressure serves as power for liquid perfusion so that some chemical components can be prevented from being adsorbed by plastic pipelines used in a conventional peristaltic pump system, medical contamination is reduced, medicine feeding efficiency is improved and medicine feeding quality is guaranteed.

Description

A kind of unidirectional perfusion device

Technical field

This utility model relates to the perfusion device field, and particularly non-absorption animal is used unidirectional perfusion device.

Background technology

Existing animal has been used traditional peristaltic pump system with perfusion device; Plastic cement pipeline wherein can produce adsorption to some chemical constituent in the medicine; Influence the administration accuracy, bring cross-contamination more possibly for the research of different pharmaceutical, influence final experimental result and reliability.

The utility model content

The purpose of this utility model is to provide a kind of unidirectional perfusion device.

This utility model is realized through following technical scheme:

Unidirectional perfusion device mainly is made up of air pump 1, Pressure gauge 2, gas tank 10, surge drum 9, delay pin 8, make-up valve 4, constant pressure regulating valve 3, fluid infusion spool 5, spring 6, adjusting bolt 7 and air filter 11.Its structure is: air pump 1 import connects air filter 11, and air pump 1 outlet links to each other with gas tank 10, and Pressure gauge 2, constant pressure regulating valve 3 are housed on the gas tank 10; Gas tank 10 connects the upper end of surge drum 9; The lower end of surge drum 9 is fitted with is detained pin 8, and the side of surge drum 9 is fixed with make-up valve 4, and fluid infusion spool 5 is housed in the make-up valve 4; Pocketed springs 6 on the fluid infusion spool 5, and spring 6 presses solidly by regulating bolt 7.

Regulate bolt 7 and through make-up valve 4 medicine is injected surge drum 9, open air pump 11, regulate constant pressure regulating valve 3, being power with the air pressure injects the medicinal liquid of surge drum 9 in the animal tracts through being detained pin 8.

The advantage of this utility model is; Whole perfusion device is liquid perfusion power with air pressure; The plastic cement pipeline of having avoided using in the traditional peristaltic pump system is to the absorption of some chemical constituent; Reduce the adsorption losses of medicine, improved the accuracy of data, guaranteed the reliability and the repeatability of experimental result.
